Moreover...
Moreover, it is known historically that the companions did not deal with one another as if they were inviolable and pardoned for all their sins and wrongdoings. Therefore, even judging by the way the companions acted and dealt with each other, it can be concluded that such sayings cannot be literally true in the way some have understood them.
If they do contain an aspect of the truth it is in indicating the legal inviolability of the companions and the sanctification which they enjoyed generally as a group because of their proximity to the Holy Prophet.
The expression of God's satisfaction with the companions in the Holy Quran, because of the services they had rendered in obeying His Command, refers to their past actions, and to God's satisfaction with them in the past, not to whatever action each one of them might perform in the future.
The Establishment of Umayyad Rule In the year 60/680 Mu'awiyah died and his son Yazid became caliph, as the result of the allegiance which his father had obtained for him from the powerful political and military leaders of the community. From the testimony of historical documents it can be seen clearly that Yazid had no religious character at all and that even during the lifetime of his father he was oblivious to the principles and regulations of Islam.
At that time his only interest was debauchery and frivolity. During his three years of caliphate he was the cause of calamities that had no precedent in the history of Islam, despite all the strife that had occurred before him. During the first year of Yazid's rule Imam Husayn, the grandson of the Holy Prophet, was massacred in the most atrocious manner along with his children, relatives, and friends.
Yazid even had some of the women and children of the Household of the Prophet killed and their heads displayed in different cities. During the second year of his rule, he ordered a general massacre of Medina and for three days gave his soldiers freedom to kill, loot, and take the women of the city. During the third year he had the sacred Ka'bah destroyed and burned.
Following Yazid, the family of Marwan gained possession of the caliphate, according to details that are recorded in the history books. The rule of this eleven-member group, which lasted for nearly seventy years, was successful politically but from the point of view of purely religious values it fell short of Islamic ideals and practices.
